Mini Review
I don't think it is a scam but I don't think it's an automated system. I prefer automated trades because of how quick they are. I sent 0.03 BTC I got 3 confirmations within an hour and my transaction was moved to processing but I haven't still got any money in my PayPal account over 8 hours later. I think it may be because I started the trade around 11:30pm Sunday evening. Ordinarily this shouldn't matter if it's an automated system but I wonder if it isn't and someone has to be online to process orders.
EDIT: Just got my payment. Worked well all in all.
EDIT 2: Turns out they send payment through the 'Pay a Seller' PayPal method rather than the 'Send money to friends and family method. The downsides are these:
1. There is a percentage transfer fee. I was supposed to receive $45.59 they sent $47.71 but I received $44.83 because of the transfer fee.
2. It is reversible. PayPal state they don't offer payment protection for 'Pay friends and family' on the other hand. So that should be much harder or impossible to reverse.
